could be pressure switch issue, not bad enough to throw a code but enough to create issues when driving.I bought a 2015 EX model last year and been experiencing the clunk and jerking problem with the the transmission. I first brought it to a local Honda dealership where they performed the 3 times flush and computer update. Didn't solve the issue. After going back a couple of times they said something was wrong with the transmission and replaced it. The van drove perfectly in the summer, but now that the weather is getting cold again( I live in Canada). , its starting to jerk and clunk again at low speeds. Anyone have any suggestions, besides going back to dealer. Thanks
its possible some of the electronic components on the old transmission, were transferred over to the new transmission.
which is why your problem has returned.
could also be temperature sensor related, are you noticing it more when the vehicle is cold and less when warmed up?
